• ]. More recently, layered double hydroxides (LDHs), a layered host–guest material, have emerged as promising inorganic nanocontainers for functional organic active species to enhance the thermal and photo-oxidation stability of interleaved organic species as well as to endow the polymer/LDH composites

• comparison with PP free of filler, the addition of HnMn′-Ca2Al-LDHs enhances the photo-oxidation stability. The photo-oxidation stability is in the following order: HALS-Ca2Al/PP > H2M1-Ca2Al/PP > MP-Ca2Al/PP > H1M1-Ca2Al/PP > H1M2-Ca2Al/PP > H1M3-Ca2Al/PP. The different co-intercalated HnMn′-Ca2Al-LDHs are

• found to enhance the thermal and photo-oxidation stability of HnMn′-Ca2Al/PP composite films, and the co-intercalated LDH/PP composite films have better overall performances compared with the systems intercalated with HALS or MP only. Conclusion In this work, we have successfully co-intercalated a
